Abstract

Plants adapt different strategies in response to WATER DEFICIT and salt stress. In the present investigation, STOMATAL RESISTANCE, SOLUBLE SUGARS, PROLINE content and PEROXIDASE enzyme activity of two species of AELUROPUS littoralis and A. lagopoides was studied in response to these two stresses. A completely randomized factorial design with four replications and different combinations of four levels of WATER DEFICIT (-0.3, -5, -10 and -15 bar), four SALINITY levels (0, 20, 25 and 30 dSm-1) and two species of AELUROPUS were used under glasshouse condition.WATER DEFICIT was induced by weight method on the basis of the amount of water lost each day. For this purpose water potential of the soil used was measured by pressure plate method and on the basis of weight of soil in each pot and the associated water potential of the soil used was measured by pressure plate method and on the basis of weight of soil in each pot and the associated water potential of a soil, the amount of water needed for each treatment was calculated. In order to keep the water potential constant daily application of water was made on the basis of weight of each pot. Salt stress was made by addition of sodium chloride to the initial water applied. One month after stresses were imposed, two-weekly interval STOMATAL RESISTANCE recorded, and after two months SOLUBLE SUGARS, PROLINE content and PEROXIDASE enzyme activity were measured. Results showed that by increasing water and salt stresses, STOMATAL RESISTANCE was first increased and then started to decrease. SOLUBLE SUGARS and PROLINE content and PEROXIDASE activity were also increased in response to both types of stresses. Interactive effects of SALINITY and water stresses were also pronounced.
